' Application filed May. '19,'

This invention relates to a check attachment for loom picker sticks and has for its object to provide, in a manner as hereinafter set forth a new and novel form of check attachment for picker sticks to increase the output of the loom for a predetermined period, as well asto materially, decrease the cost of maintenance in connection with the operation of the loom, and furthermore to overcome the use of check straps now' generally employed for checking the picker sticks, as such checklstraps quickly dete-- riorate or become damaged resultingin increased cost of maintenance and further reducin termined periods.

Furtherobjects of the invention are to provide, in a manner'as hereinafter set forth a check attachment for loom picker sticks which is simple in its construction and arrangement, strong, durable, thoroughly ef-' ficient in its use, readily installed with respect to the battery right or battery end and the left or lever end of the 100111, and comparatively inexpensive to manufacture.

' With the foregoing and other ob ects in view, the invention consists of the novel construction,combination andarrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appendech In the drawings wherein like reference characters denote corresponding parts throughout the several views a Figure 1 is an elevation of a end of the lay,

The picker stick 2 is arranged at the right or battery end of the loom and the picker stick 3 at the left or lever end thereof. Supported by the frame 1 is a lay'ei and whichhas each of its ends bifurcated and'the bifurcated ends of the lay 4t attlie battery end of the loom is indicated-at 5 and the bifurcated end arranged atthe lever end. of'the loom is indicated at 6.- The furcation in the end 5 is designated at 7 and that in the end 6 at 8. The

picker stick Q'extends up through the furcation 7 and the picker stick 3 extends up through the furcation 8; The shuttle boxes are designated at 9. The picker sticks'2 and 3 are'pivotally connected as at 10. .The bifurcated end 5 of the play 4 provides a pair of arms 11, 12 and the bifurcated end i 6 provides a pair of arms 13, 14. v The picker sticks 2,3 are operated in the known manner. The foregoing elements are of known construction with the exception of the manner in which arm 12 is formed and against which is secured the quill chute 14; v

The pickerstick check attachment for looms, in accordance with this invention, in-

controlled binder of the lay 4 and a pair of spring controlled binder elements supported below the plate 4 at the end 5 thereof chute 14.

The pair of binder elements positioned at the end 6 of the lay 4 are indicated generally bythereference characters 15 and 16 and and top of the quill 'areoppositely disposed with respect to each other and further are arranged against the lower face of the lay 4 and normally extend across the furcation 8, see Flgure 4. As the binder element is constructed in the same manner as the bind'er'element l6,'but one Wlll be described, as the descriptlon of one.

outer end of the shank 18 merges into theinner end of the check portion 17. The shank 18 is pivotally connected at the longitudinal median of the arm 13 or 14; The outer side of the check portion 17 forms a continuation of the plane of the outer side of the shank 18 and the forward end, of the latter on its inner side is rahbeted as at 20. The outer end of the check portion 17' is squared as indicated at 21 and the inner outer corner of said. check portion 17 is rounded as at 22. The inner side of the check portion 17 extends upon two different inclinations as indicated at 23, 24 and the inclination is towards the outer side of the check portion 17. The inclined portion 23 formed on the inner side of the check portion 17 is of greater length than the inclined portion 24 and the latter extends at a greater inclination than the inclined portion 23. The'end 21, as well as theinner side of the check portion 17 has secured thereto a wear strip 25 of any appropriate material. The wear strip'25 extends from the rabbet 20 and has its outer face flush with the inner side of the shank 18. Secured to the arm 13, by a hold fast device 26 is the inner end of a controlling spring for the binder element 16 and said spring is indicated at 27. and is so formed whereby the inner portion thereof will be arranged above its forward portion. The inner portion of the spring 27 is indicated at 28 and the forward portion 29. The forward portion 29 is upon a compound curve and bears against the outer side of the check portion 17 of the binder element 16. Secured to the arm 14 by the hold fast device 30 is the inner end of a controlling spring 31' for the binder element 15. The controlling spring 31 is set up in the same manner as the controlling spring 27. The

' springs 27 and 31 set to normally maintain the binder elements 15 and 16 in the path of the picker stick 3. The binder elements 15 and 16 have their outer ends positioned inwardly with respect to the outer ends of the arms 14 and 13. The controlling springs 27 and 31 further act to maintain the check portion 17 of the binder elements 15 and 16 in abutting engagement. The setting of the inner sides of the binder elements 15 and 16 in the manner as referred to permits the free entrance'of the picker stick 3 between the check portions 17 for the purpose of shifting the binder elements 15 and 16 in opposite directions and againstthe action of their controlling spring and these latter act to cause the check portions 17 to bind against the picker stick 3 and check the same. WVhen the picker stick 3 moves from between the check portion 17 the springs 27 and 31 cause the binder elements to move towards each other to the extent whereby the check portion 17 thereof will abut.

The outer portion of the arm 12 isof less height than the arm 11 but the upper face ofv the said outer portion of the arm 12 is flush with the upper face of the arm 11. By setting up the outer portion of the arm 12 of less height than the arm 11a shoulder 32 is provided, see Figure 1, and against which abuts the quill chute 14, and the latter is provided with an extension 33, se-

appropriate distance and is spaced from the extension 33, as well as being arranged below the same. The arm 39 provides asupport for one of the binder elements positioned at the battery end of the loom.

Secured to the lower face of the arm 11, by the hold fast devices 40 is a spacing block 41 formed with. openings 42 for the passage of the hold fast devices 40. The spacing block 41 at its rear end has a reduced extension 43, a shoulder 44 and a beveled outer lower corner 45 which forms a clearance. The other binder element employed at the battery end of the loom is. pivotally supported from the spacing block 41."

The binder elements arranged at the battery end of the loom are indicated generally by the reference characters 46, 47 and when arranged in position are oppositely. disposed with respect to each other. As each of the binder elements 46, 47 is of the same construction, but one will be described, as the description of one will apply to the other. The binder element 46, as well as the battery element 47 has its inner side inclining away from its outer side from its inner towards its outer end and said inner side isv indicated at 48. By this construction the binder element gradually decreases in width from its inner towards its outer end, The outer side 49 of the binder element is squared, as well as its 52. The inner side 48 of the binder is formed with a vertically disposed shoulder 53. Abutting against said shoulder and extending around the corner '52 and to the forcentrally of its reduced or inner end is formed with an opening 55. o

The binder elements 46 and 47 are spring controlled and that part of each to which the strip 54 is connected and indicated at 56 is termed a check portion. The controlling springs for the binder elements 46 and 47 normally maintain them in abutting position and across the furcation 7. See Figure 2. The controlling spring for the binder element 46 is indicated at 57 and the controlling spring for the binder element 47 is indicated at 58. The inner end of the spring 57 is secured to the arm-11 by the hold fast device 59 and said controlling spring includes an upper inner portion 60 and a lower outer portion 61 which bears against the outer side of the binder element 46 at the outer part thereof. The spring 57 is curved soar; to provide the inner and outer portions 60, 61 respectively. The controlling spring58 for the binder element 47 has its inner end secured to the vertical arm of the member 38 by the hold fast device 62. The spring 58 is.

curved and extends inwardly towards the binder element 47 and the outer end of the spring 58 bears against the outer side of the element 47 at the outer end thereof.

The binder element 46 is arranged below the spacing block 41 and has its inner end pivotally connected therewith by a pivot bolt 63 which extends through the opening 55 in the binder element 46 and engages in the spacing block 41. The binder element- 47 is pivotally connected to the arm 35 by a pivot bolt 64 which extends through the opening 55 in said binder element 47 and also extends through an opening 65 formed in the arm 39. A securing nut 66 is carried on the lower end of the bolt 64 and a washer 67 is interposed between the head of the bolt and the binder element 47. A washer 68 is interposed between the block 41 and the binder elements 46. A hold fast device 69 extends through the opening 36 and through the slot of the arm 37 whereby the support 88 is connected to the lateral portion of the extension 33. The binder elements 46 and 47 oppose each other and the arrangement of the spacing block 41 and the height of the support 38 provides for such arrangement, see Figure 3. The setting up of the binder elements 46 and 47 in the manner as shown that is to say providing them with the inclined inner sides permits of the picker stick 2 easily entering between said binder elements and the controlling springs for these latter will act to check the picker stick 2. I When the picker stick 2 moves away from the binder elements, the controlling spring for these latter shift them into abut-ting engagement at the check portion 56. The binders at the lever end of the loom aline with the binders at the battery end of the loom. Each pair of binders close when the picker stick is jerked forward and checks the picker stick about two inches from the end of the lay when the picker stickdrops back.

i The lay 4, as is well known, is not constructed alike at both ends. At the left or lever end of the loom the lay is about three inches widewith a slot in it for the picker stick'to work in and is level on its lower face which makes it possible for binders to be fastened to the bottom of the lay, one on the front and one on the rear side positioning the binders on a level with each other and with one opposing the other. Thatend of thelay at the right or battery end of the loom is about one and one half inches wide, as the front part of such end'o f the lay has been cutaway to allow the quill chute to be placed in position, whereby provision is only had to fasten the back or rear binder in position to the .lower face of the lay. The front binder has to be fastened to the quill chute there being no front part of the lay to fasten the front binder to. The quill chute is arranged about one and one quarter of an inch below the lower face of the lay, therefore it becomes necessary to use a spacing block on the lower face of the lay at the back, to bring it down to a level with the quill chute,then by fastening the block to the bottom of the lay'at the back thereof, it positions the, back binder on a level with the front binder which operates on the support fastened to the quill chute, and by this arrangement the front and back binders are in alignment and, oppose each other. 1

It is thought the many advantages of a picker stick check attachment fur looms in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described yet it is to be understoodthat changes in the details of construction can be had which will fall within the scope of the invention as claimed.
